GENERAL DESCRIPTION

The SGM2553E is a single channel power distribution switch. The switch operates from a wide range of 2.5V to 5.5V supply voltage, and is controlled by the EN pin.

A 90mΩ low RON N-MOSFET is integrated. The small size and quiescent current make the device very suitable for space limited, battery-powered applications.

A number of protection features are provided in the device including soft-start, over-current protection, adjustable current limit and thermal shutdown. This device provides a programmable current limit threshold between 100mA and 200mA through the RILIM. The internal reverse-voltage function will protect devices on the input side of the switch. Fault conditions are indicated by the nFAULT pin. The SGM2553E has quick output discharge function in disable status.

SGM2553E is available in a Green TDFN-2×2-6L package. It is rated over the -40℃ to +85℃ temperature range.
